Description
Technical field
The present invention relates in ring spinner (ring spinning machine) and ring ingot twisting mill (ring
Twisting machine) in production and winding yarn device, wherein yarn by twisting element rotation and due to spinning
Hammer and spool generate speed difference and be wound up on spool.
Background technique
Ring-rotor-system of traditional ring spinner and ring ingot twisting mill equipped with the twisting insertion for line
(ring-rotor-system).Due to the rotation of spindle, so that rotor rotates, middle line is suspended in rotor and rotor spirit
It is fixed on ring livingly.Such as be capable of forming the rotor for simple coil therefore do not have intrinsic driving, but passed through by spindle
The yarn of suspension in the rotor drives.By high friction of the rotor on ring, by the air drag and line guided rings of ring and
The air drag of ballooning of yarn between rotor makes rotor keep lagging behind the speed of spindle, this causes the coil of wire around spool
On.
During rotor moves on ring, due to the centrifugal force of generation, rub between ring and rotor.Due to rotor
Quality it is low and cannot effectively radiate, this leads to the rate limitation of rotor.If the speed of rotor further increases, rotor will
It is heated to the degree for shining and being broken.In addition, this leads to the fusion of thermoplastic fiber materials and the cotton material containing honeydew
Softening.
Ring spinning processes productivity limitation mainly as caused by ring-rotor-system and depend on ring, rotor and
Yarn.Productivity, which improves, means that the speed of spindle improves, however, will lead to currently available ring and rotor when overstepping the extreme limit
Abrasion acutely increase.
The limitation of spinner velocity means that the conveying speed of line cannot be improved further, so that existing ring-rotor-is
System limits the production capacity of ring spinner and ring ingot twisting mill.
The winding and twister of known ring spinner or ring ingot twisting mill from the WO2012/100964 of applicant,
The friction between ring and rotor is wherein eliminated by magnetic suspension, this extends the service life significantly and reduces impact force.Have
The annular stator of superconductor is configured to, middle ring coaxial with spool with stator cooling device in a manner of identical with ring-shaped rotor
Shape rotor can rotate and be generated relative to stator magnetic field and have endless yarn induction element.When the superconductor of stator is cold
But to when being lower than transition temperature, the magnetic flux for coming into stator of rotor is frozen, makes it possible to be realized by means of magnetic suspension
Initially by autostable passive (passive) support of the rotor of mechanical support.Due to the contactless support of the rotor of rotation,
It can be omitted traditional ring-rotor-system ring as important component due to generating frictional heat and limit production rate.Instead of
Ground, the entire rotor with yarn induction element can quickly rotate now, wherein rotation there is no friction-in addition to faint
Magnetic friction except-therefore allow much higher spindle speed.
However, being formed as the rotor of magnet ring has sizable self weight, must be also accelerated during focusing on spindle starting certainly.
In addition, the magnet ring of free floating cannot be installed in the housing, so that the high speed rotation for going to 30,000 turn with about per minute 20,000
The magnet ring turned causes security risk to device operator.Finally, the yarn induction element for being installed on magnet ring constitutes imbalance, spins
The speed of hammer more increases, which becomes more problematic.
It is a kind of for twisted fibers material and in ring spinner and ring ingot twisting mill therefore, the purpose of the present invention is to create
The device of yarn or cord that middle winding generates, the device can make the machine quick start and closing of high productive capacity, and
In addition the safety of operator is improved.In general, the present invention is based on further increase ring spinner and the twisting of ring ingot
The purpose of the productivity of machine.
Summary of the invention
The above problem for the winding of ring spinner and ring ingot twisting mill and is added by the feature with independent alternative 1
The method of twist device and the feature with independent alternative 14 solves.Advantageous modification and further development are documented in subordinate
In patent formula.
According to the present invention, the winding and twister of ring spinner or ring ingot twisting mill include: at least one stator,
Including stator cooling system and at least one superconductor；At least one rotor generates magnetic field；And rotatable spindle,
The wherein rotor and stator is with the spindle arranged coaxial and the rotor and the stator are formed as follows:
So that form annulus gap between the rotor and the stator, the annulus gap and the spindle arranged coaxial and to
The line of winding can bypass (circulate) in the annulus gap.
The air gap of formation is formed in an annular manner, wherein the position of air gap and extend in device operation during as follows
It is formed: so that line to be spooled is wound up on the rotating bobbin of ballooning of yarn lower end by air gap.For example, air gap can have
There is the width of 2mm to 3mm.By the rotation of spindle and sleeve, line is taken away with bypassing in known manner, middle sleeve and line
Axis is placed on spindle together.Due to the windage of ballooning of yarn, line occurs slower around the quick rotation than spindle,
Line is twisted and weaves in winding.
Particularly, the rotor and/or the stator can particularly have at least one with the spindle arranged coaxial
A endless yarn induction element, wherein the yarn of the yarn induction element of the rotor and/or the stator guides
Element is configured in a manner of defining the air gap.Therefore, yarn induction element formed annular define element, wherein the line bypassed
It is slided on the surface that one or two defines element.The friction generated in this process is minimum, very high so as to realize
Spindle speed.It windage and is together defined between the line bypassed and spindle rotation with the friction of yarn induction element
Relative velocity.As a result, the surface texture of endless yarn induction element has determined spinning quality using friction.
Compared with prior art, the similar device that yarn induction element does not form ring or bypasses together with line, but only shape
Element is defined at the expansion (expansion) that air gap is configured and limited with spindle axis coaxle.As a result, it is no longer necessary to rotor with
Line is rotated around spindle axis together, although further development according to the present invention need not exclude the rotation.It is attributed to following explanation
The magnetic suspension of rotor can be in the feelings of not mechanically moving component because floating rotor can position in a non contact fashion
Guide line under condition.Although rotor can be positioned particularly in a relatively unrotatable manner as described further below, so that
Rotor no longer rotates, but this term will be used as generating magnetic field herein and below and configure with spindle axis coaxle
Element general terms synonym.Therefore, the concept of rotor is more related to contactless support not as rotation member
The function of part.In the general further development, additionally it is possible to tolerate that rotor will be slided on rotor during being run due to device
The friction of line and gradually rotate.But it is different from former situation, due to being attributed to the low friction with the yarn induction element of rotor,
Actually line can be made to rotate immediately, therefore device can significantly more quickly start.
Yarn induction element is formed as follows: to be spooled convenient for guidance horizontal (i.e. edge is around direction orientation)
Line, and selectively vertical (i.e. along spindle axis orientation) line of guidance.This is for example since yarn induction element passes through it
On rotor and/or stator configuration formed for line deflecting element and occur.In order to avoid line is torn during operation,
Yarn induction element has been capable of forming smooth surface appropriate and has particularly formed circular shape.In spinning process, line
It is slided on the smooth surface of yarn induction element along around direction, wherein yarn induction element prevents line to be wrapped in particularly not
It is in the rotor and/or stator formed in rotational symmetry.Therefore, yarn induction element is for making line far from winding and twister
Potential surface imperfection (irregularity) and edge.
In addition, rotor and stator can have multiple endless yarn induction elements, as long as air gap is by least the one of rotor
At least one yarn induction element of a yarn induction element and/or stator defines.Due in addition to yarn induction element it
Outer rotor and stator are not required to be formed in an annular manner, so their arranged coaxial relates generally to the yarn being previously mentioned guidance
Element.In addition, subdivision mentioned below is particularly capable of configuring along the circumference of the coaxial circles around spindle axis.
As described in more detail below, rotor can include the subdivision at least with the permanent-magnet material for generating magnetic field.This
Mean that rotor is at least partly magnetized or with permanent magnet.Other subdivisions of stator and rotor also can be by other non-
Magnetic material is made.It is especially true for yarn induction element.In order to promote the suspension of rotor, it is particularly capable of turning using reduction
The material of sub- weight.
In order to form superconducting state in stator region, it is described fixed that stator must be allowed for the magnetic flux of rotor to enter
Son, and must have the cooling device for cooling down stator.It is this be used to form it is low needed for the superconducting state of superconductor
The stator cooling device of temperature is formed as follows: it can reduce the temperature in the superconducting areas of stator, low until being reduced to
In the transition temperature of used superconductor.In variant of the invention, cooling device is capable of forming to bathe cryostat
(bath cryostat) can fill the bath low temperature if being higher than the high-temperature superconductor of 77K using transition temperature with liquid nitrogen
Thermostat such as carries out cooling vaporation-type wherein also using other cryostats in other modifications by means of cold air
Cryostat, or do not need the refrigerator cryostat of freezing liquid.By the difference is that being imitated using different physics
Also the cryostat should can be made redundantly to interconnect to improve system come the various combination of the multiple cooling devices to freeze
Reliability.In this case, superconductor can be surrounded and/or be coated by heat insulator appropriate so that cooling loss is minimum
Change, which is capable of forming as a part of stator cooling device.
On the one hand since winding according to the present invention and twister no longer need mounting ring or similar device on rotor
As yarn induction element, on the other hand due to also no longer needing the rotation of rotor, injustice is substantially eliminated so being capable of forming
The rotor of weighing apparatus, the rotor can be easily positioned by the user in a manner of inherently stable.
Particularly, rotor and stator can be formed as follows and configure: so that rotor during operation can be due to
Magnetic suspension and position in a non contact fashion.This support for being interpreted as rotor is free floating, therefore in the superconduction area of stator
It is contactless after domain is cooling.By keeping the optimum distance of delimited area and rotor and stator relative to each other, and pass through
Rotor is consolidated by making the temperature of superconductor fall below transition temperature through the magnetic flux tube of the non-uniform magnetic-field of stator
It is fixed, so that being passively supported in two kinds of situations that rotor is not rotated and rotated for the inherently stable of rotor is all possible.Cause
This, can omit the complex control and/or sensor unit of the active bearings control for rotor.Ensured not by optimum distance
There are abrasion, and which results in high reliability and robustness.Due to the contactless support of rotor and as substantially limiting productivity
Traditional ring-rotor-system ring omission of the component of (since it generates frictional heat), can increase line and spindle significantly
Rotation speed, this, which causes to increase relevant productivity sharply to the possibility of spool diameter in turn, improves.
The passive support of the inherently stable of the generation of rotor from by position and restoring force caused by changing in orientation of and
Balance of the magnetic flux tube to the fixed force of the superconductor of stator.
Rotor and/or stator can be formed as follows: rotor passes through produced relative to the rotation around spindle axis
Magnetic field fix (pin) in stator.This can be realized by the magnetic field of the rotor around spindle axis not symmetrically.In addition,
The superconducting areas of stator can replace in the circumferential with usual conductive or insulation region and/or superconducting areas can have
Defect.Superconducting areas is to quantify magnetic field in the form of capable of being attached to the magnetic flux tube of defect.It is attributed to the magnetic flux gradient generated, is produced
Retentivity is given birth to.Then, the rotation of rotor will only be able to resist the retentivity, which will not pass through yarn induction element table
The low friction of the line bypassed on face is overcome.Therefore, rotor is not only free floating, but also with relatively unrotatable
Mode positions, so that need not accelerate additional quality during device starting.
Particularly, rotor can have one or more subdivisions, and subdivision has the permanent-magnet material for generating magnetic field.Even if
With the single subdivision for generating magnetic field, rotor also can be steadily supported.In two or more sub-portions with permanent-magnet material
In point, generated magnetic field obtains the multipole characteristic for promoting relatively unrotatable support.Subdivision can for example be designed to
The interval of rule is configured at the bar shaped of endless yarn induction element or the form of cylindrical magnet.In this case, Neng Gouyou
Selection of land selects pole span (polar pitch) in a manner of being greater than air gap, to guarantee that magnetic field is efficiently entering the superconducting areas of stator.
Between them, non magnetic section can formed in particularly lightweight mode can be configured to promote to suspend.Equally, it can be omitted completely
Interlude is further to mitigate the weight of rotor.In the simplest case, rotor can be the guided rings for line, draw
Two or more bar shapeds or cylindrical magnet are installed on lead ring.
In addition, stator can have two or more superconduction subdivisions, these subdivisions in the circumferential direction of spindle relative to
It is separated from each other.Therefore, superconductive element does not need particularly to extend in whole circumference, enables stator cooling system significant
Ground is more compact and energy saving.Superconduction subdivision can have II type superconductor as superconductor.In one embodiment, these
Superconduction subdivision can be rare-earth barium copper oxides (SE) the BaCuO group from such as yttrium barium copper oxide (YBaCuO) or come from
The pottery high-temperature superconductor of bismuth-strontium-calcium-copper oxide (BiStCaCuO) group.With the sheet of superconductor in the subdivision of stator
The modification of invention be also it is possible, wherein superconductor have the transition temperature more even higher than already mentioned group.Therefore, energy
The performance parameter of cooling device is enough reduced, this causes the energy efficiency of the winding and twister to improve.In this case,
Superconduction subdivision is normally used for the heat insulator for minimizing cooling loss and surrounds.
Usually conductive and/or insulating materials section can be configured between superconduction subdivision.However, in order to save material,
Also these interludes can be omitted completely.In this case, stator only by endless yarn induction element and is configured at these yarns
Two or more superconduction sub-portions of line induction element are grouped as.Particularly, superconduction subdivision can be in the periphery of spindle, i.e. edge
Configured at regular intervals around the circle of spindle axis.This allows the particularly stable installation of rotor.
For each superconduction subdivision of stator, rotor can have the appropriately configured subdivision with permanent-magnet material.Cause
This, a superconduction subdivision of stator and the subdivision of rotor position with being respectively opposite each other, this can ensure the spy of magnetic flux line
It is not effectively unfixed.It is desirable that corresponding subdivision can have equal or comparable extension in the circumferential.Particularly, rotor
There can be lucky three subdivisions with stator.Generated three-point mount allows to carry out rotor in entire spinning process special
Not stable contactless support.
According to further development, rotor and stator can configure in a co-planar fashion, wherein stator surrounding rotor and line
Air gap is conducted through from top.Herein and hereafter, term " top " and " lower section " are interpreted as relative to standing on installation table
For the ring spinner or ring ingot twisting mill in face.Usually it is directed on sleeve from top by fibrous material and/or line
Spool, in this process due to line it is quick rotation and form so-called ballooning of yarn.In coplanar arrangement, rotor is in radial direction
It is located in stator on direction, wherein particularly, the endless yarn induction element of rotor is located at the endless yarn induction element of stator
It is interior.From inside along outward direction from, which can seem especially as follows:
A) section with permanent-magnet material of rotor,
B) the endless yarn induction element of the encirclement section of rotor,
C) air gap,
D) the endless yarn induction element of stator, and the yarn induction element relative positioning of rotor and surrounds rotor,
And
E) superconducting section of stator.
This configuration is particularly compact and makes it possible to effectively cool down superconducting areas.Can in a particularly simple way by
Line by the air gap between endless yarn induction element and is wound up on the spool below rotor from top guidance.In the process
In, line would generally slide on the surface of the yarn guided rings of rotor, enable the surface advantageously in a smooth manner
It is formed.Furthermore it is possible to by for example by rounding in a manner of design the sections of yarn guided rings, so as to prevent line under ring
It is torn on edge.
According to the further development of substitution, rotor and stator can ground axially spaced from one another configured in parallel, wherein by line
Pass through air gap from exterior guiding.In this case, term " inside " and " outside " should be seen as spindle axis.
Rotor can be configured to be located above or below stator until the axial distance away from stator and rotor is sufficiently small, so that the magnetic of rotor
Field is able to enter the superconducting areas of stator.The axial distance being attributed between rotor and stator, in addition will form air gap (from outside
Line guidance is passed through into the air gap).In this process, the yarn induction element of rotor and stator is at least partly in vertical direction
It is upper, i.e. positioned relatively to each other along spindle axis.In further developing previous, yarn induction element is in such case
Under be capable of forming circular edge contour also to avoid the tearing of line.In such another further development, two
Stator can configure as follows: so that the delimited area that they are positioned is respectively positioned to and rotor axially opposite each otherly
Axial delimited area is opposite.Therefore, two annulus gaps are formed, pass through an air gap or another gas wherein line can be guided
Gap.In this case, the further development of illustrated yarn induction element should correspondingly be applied.
According to further development, the surface of the yarn induction element of rotor and/or stator contacted with line can be coated
At least partially.Particularly, the entire yarn induction element of rotor and/or stator can be coated.It in this case, can be with
Ensure to select coating with the mode of the expectation friction of the line bypassed around speed for imagination, in this process with desired
Spin quality braided wire.For example, coating can have in Ra=0.025 (grinding) according to DIN EN ISO4287:2010-07
Average roughness value Ra (μm) to Ra=0.5 (pre-grinding) range.
In addition, yarn induction element can be made of plastic material or light metal, or including plastic material and/or light gold
Belong to.Such yarn induction element be capable of forming for low weight and at the same time having enough stability and heat-resisting
Property, make it possible to guarantee while ensuring low abrasion level the suspension of rotor.
According to further development, stator can be kept by winding with the holding meanss of twister, wherein the holding
Device is formed with fixed position, and the spindle with spool relative to fixed stator shaft orientation, can be moved i.e. along spindle axis
It is dynamic, by Yarn homogeneous to be wound up on spool.However, in another embodiment of the present invention, the spindle with spool
It is fixed, and stator holding meanss are connected to stator shift unit, so that being used for ring spinner and ring ingot twisting mill
Winding and twister can axially, i.e. be moved along spindle axis relative to spindle and spool.
In order to form stator holding meanss, the radial direction between spool and stator or the interior radial delimited area of rotor should be kept
Distance, the distance depend on one with small radii in stator or rotor.In order to which yarn or cord are being wound up into spool
Period keeps the air drag generated by ballooning of yarn equal, and the embodiment of the winding and twister with movement can be with
As under type ballooning of yarn upper end formed line guiding piece: make line guiding piece also kept by stator holding meanss or line guidance
Part is directly fixed on stator, and line guiding piece is shifted in the axial direction together with winding and twister.Therefore, it is winding
The expansion of thread balloon at a distance from rotor and therefore of process middle line guiding piece is kept constant.
The above problem is also solved by a kind of ring spinning or ring ingot twisting method, wherein twisting and being then rolled up fiber
Material is provided with winding and twister as described above, same with the rotor and the stator by rotor holding meanss
The axis and mode being separated by a distance keeps the rotor, falls below institute for the temperature of the superconductor of the stator
The transition temperature of superconductor is stated, and dress is then kept by the rotor before actual spinning and twisting process start
The release rotor is set, as long as reaching the superconducting state of the rotor.
By making rotor and stator initially keep a distance, substantially it is convenient for opening for machine in the solution proposed
It is dynamic, wherein the distance is scheduled or optional in structure.
In the ring spinning or ring ingot twisting method mentioned, spindle can be driven with a speed around spindle axis, for this purpose,
The friction of the line and yarn induction element that bypass is not enough to overcome relatively unrotatable magnetic support.In other words, by magnetic flux line
Fixation caused by be higher than the line bypassed that generates in operating process about the restoring force of the rotation of rotor and draw in the yarn of rotor
Frictional force on guiding element.
Illustrated winding and twister and ring spinning and ring ingot twisting method allow with the yarn of constant quality
Significantly improve the speed of spindle.In addition, ring spinner or ring ingot twisting mill can be in the case where postponing no any time
Starting, so that low-quality yarn will be refused now.

Type and embodiment can also apply to the respective element in remaining attached drawing.
The embodiment schematically shown in a side elevational view in fig. 1 is the section of ring spinner 17 comprising according to
Winding and twister 18 of the invention.Stator 1 and spindle and/or spindle axis 7 at least one superconductor 19 are same
It configures to axis, and is cool below the transition temperature of superconductor 19 by stator cooling device 9.At this illustratively into one
The stator 1 that 2 lower section of rotor is arranged in step development is kept by the stator holding meanss 10 only symbolically shown.However, due to
Magnetic suspension is also possible in hanging position, so further including embodiment and a stator of the stator arrangement above rotor
It is arranged in rotor lower section and embodiment of another stator arrangement above rotor.
Rotor 2 configures parallel and axially spaced from one anotherly with stator 1, so that they do not contact each other and by rotor

There is a yarn induction element 13, yarn induction element 13 is also formed and coaxially arranged with spindle 7 in an annular manner.As a result, in shape
At guide line 8 in the air gap 14 between yarn induction element 3 and 13.It is clear that according to configuration and formed, rotor 2 and
Both stator 1 can include the other or yarn induction element that is differently formed, if the element in an annular manner and around
It is formed to spindle axis coaxle and guarantees line being reliably directed to spool 6 from outside by air gap 14.In addition, yarn draws
The configuration of guiding element must adapt to the relative configuration of rotor 2 and stator 1.Most of all, yarn induction element allows for making
Line 8 freely bypasses, and is therefore not formed as the enclosed rotor that must be bypassed together with line around spindle axis.It therefore can be by freedom
The rotor 2 of floating is magnetically fixed in stator 1, so that rotor 2 is fixed in fixed and contactless mode during device is run
Position.Due to needing to accelerate there is no quality from now on, which can start in the case where no delay.
For winding starting and closing with twister 18, rotor 2 passes through rotor holding meanss 12 and stator 1 coaxially
A distance is kept, the temperature of stator 1 falls below the transition temperature of superconductor 19 and subsequent rotor holding meanss 12 are released
Put rotor 2.For this purpose, the mechanical connection 24 schematically shown can disconnect during operation.
The yarn guidance that yarn 8 passes through thread guides 4, continues through air ring constriction ring 5 and cross rotor 2 from outside

The special further development that stator and rotor are illustrated in Fig. 3, for opposite cannot turning for rotor
Dynamic, contactless support.When yarn induction element 3 and 13 is formed in an annular fashion, the not only permanent magnetic region 21 of rotor 2
And the superconducting areas 19 of stator 1 is all only formed in a manner of section.In the unrestricted further development shown in, rotor
2 include three subdivision 21a-c with permanent-magnet material, and three subdivision 21a-c are along the inner circumferential of yarn induction element 3 to advise
Interval then configures and can for example be formed as shown as bar shaped or cylindrical magnet.In this case, magnet is solid
The element is carried due to yarn induction element 3 and during operation.Alternatively, yarn induction element 3 itself can include forever
Magneton part, such as the magnetised section as becket.In the embodiment being initially referred, by being formed for example by plastic material
Or made of light metal and there is the yarn induction element 3 of low thickness to be capable of forming the particularly lightweight rotor 2 of quality.Therefore,
Through magnetic suspension can be reached with low field intensity.
Corresponding to rotor 2, there are three superconduction subdivision 19a-c for the tool of stator 1, and three superconduction subdivision 19a-c are along yarn
The periphery of induction element 13 to configure at equal intervals, and size about superconduction subdivision and configuration can with just with rotor 2
The opposite mode of permanent magnetism subdivision 21a-c formed.Superconduction subdivision 19a-c can be by stator holding meanss or the cooling dress of stator
Holding is set, and itself keeps yarn induction element 13.Also yarn induction element 13 can be omitted.Diagram is respectively provided with three
The configuration of subdivision allows the stable contactless support of rotor, and rotor is additionally due to magnetic flux line is fixed to superconduction subdivision 19a-
C and it is relatively unrotatable.As shown in figure 3, line 8 can be guided from top by between two yarn induction elements 3 and 13
Air gap 14 simultaneously makes line around the air gap.Therefore, it is no longer necessary to accelerate rotor 2 during ring spinner starting and shut down
Period makes the rotor slow down.Due to the low friction of the line 8 bypassed, the very high speed of spindle 7, this energy can be in addition realized
Enough improve the productivity of ring spinner.Since rotor 2- is no longer rotated regardless of title-, operator is not had more
More risk of injury.
